Abstract
The utility model discloses a kind of Roadway Sub-Level Caving hydraulic support, before there is rectangle base plate, its head and the tail of rear base are hinged together, affixed two upright tune frame jack on rear base, affixed upright tune frame jack on front base, before there is rectangle top board, its head and the tail of rear back timber are hinged together, frame jack piston rod top is adjusted to be hinged on rear back timber for two wherein on rear base, tune frame jack piston rod top on front base is hinged on front back timber, the articulated lower double link of its other end of upper connecting rod that rear top beam rear end is hinged, the other end of lower double link is hinged on the hinged seat of rear base afterbody respectively, hinged its other end of advancing jack of positioning seat is hinged on the tail end of rear base.The utility model can adapt to half-edge coal seam puts coal Production requirement along base plate, and supports the use with reprinting scrapper conveyor, and performance safety is reliable, improves the rate of extraction in half-edge coal seam exploiting field, can realize safety, mechanical coal mining efficiently.
Description
Technical field
The utility model belongs to the hydraulic support, particularly a kind of Roadway Sub-Level Caving hydraulic support that use at half-edge coal seam laneway coal mining.
Background technology
Half-edge coal seam is not only distributed more widely in China, and occurrence condition is complicated, and mine quantity is more.Steeply-inclined seam mining is not only China, a large production technique difficult problem of the current coal industry in the Ye Shi world.Not only there is the problem that safety factor is low, production scale is little in current steeply-inclined seam mining, but also it is low to there is the rate of extraction, the problem of serious waste coal resources.According to investigation, China's half-edge coal seam working section recovery is at present also less than 30%.Therefore, the exploitation of half-edge coal seam is the difficult problem that Coal Mining Technology is comparatively given prominence to always.Coal authorities at different levels of China and coal enterprise all try every possible means to capture this hang-up of Mining Methods In Steep Coal Seam by fair means or foul.
Coal is released by frame tail tail boom Sub-Level Caving by Steep Seam coal support usually that developed at present, and to undesirable by frame tail drawing effectiveness compared with hard coal seam with ature of coal, the rate of recovery is not high.
Utility model content
The purpose of this utility model is to provide a kind of Roadway Sub-Level Caving hydraulic support, half-edge coal seam puts coal Production requirement along base plate can be adapted to, and support the use with reprinting scrapper conveyor, performance safety is reliable, improve the rate of extraction in half-edge coal seam exploiting field, safety, mechanical coal mining efficiently can be realized.
The purpose of this utility model is achieved in that a kind of Roadway Sub-Level Caving hydraulic support, before there is rectangle base plate, its head and the tail of rear base are hinged together, affixed two upright tune frame jack on rear base, affixed upright tune frame jack on front base, before there is rectangle top board, its head and the tail of rear back timber are hinged together, frame jack piston rod top is adjusted to be hinged on rear back timber for two wherein on rear base, tune frame jack piston rod top on front base is hinged on front back timber, the articulated lower double link of its other end of upper connecting rod that rear top beam rear end is hinged, the other end of lower double link is hinged on the hinged seat of rear base afterbody respectively, hinged its other end of advancing jack of positioning seat is hinged on the tail end of rear base.
Forward and backward back timber of the present utility model plays the effect of supporting roof coal body, realizes certainly dividing a word with a hyphen at the end of a line away of support after adjusting frame jack contraction support to fall frame by advancing jack.Side plate is regained rear broken colliery and is slipped into the scrapper conveyor arranged between support two base along base plate, utilizes reprinting scrapper conveyor overlap joint ribbon conveyer to be transported by coal.Top coal is put and is only run into spoil, and side plate stretches out and blocks spoil and pour in support, and receive advancing jack, frame reach falls in support, and what proceed next circulation puts coal work.
The course of work of the present utility model is:
Hydraulic support falls frame and receives advancing jack, and support rises frame and supports, and support is anterior for splitting explosion, and stent support crushes top coal further, receives side plate Sub-Level Caving, sees that cash stretches plate, falls frame and moves frame and realize one and put coal and circulate.
The utility model support manufactures and designs according to the specific demand of Special Coal Seam, and the applicable half-edge coal seam that can become reconciled puts the demand of coal along base plate.
The utility model achieves fine low adaptation half-edge coal seam puts coal Production requirement along base plate, and supports the use with reprinting scrapper conveyor, and performance safety is reliable, improves the rate of extraction in half-edge coal seam exploiting field, achieves safety, mechanical coal mining efficiently.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
